The enlarged the operating fluid, causing it to impinge central hole G receives the looselyfitting 50 upon the serrations. If shrouded disks are boss H.

The main casing inclosfoot plates K are secured to the sole-plate A by the bolts L and are adjusted as may be required by means of the set-scnews M, provided with the clamping-nuts N. The adj ust-able stuifing-boxes D and the foot-plates the casing may be adj and accurately in the e place in the independent bearings B and for the purpose of maintaining the disk in its correct relative position, which is slightly out of the center, so as to form the smaller passage nearest to the pressure-chamber and ad.- j ustable director-plates. The circumferential portion of the casing may either be an integral part of a side plate F or may be bolted theretowiththe clamping-bolts P, or 3 the side pl portion. The disk Q, having serrations R, is securedto the spindle C. The said. serrations are provided with impelling and following surfaces, the impelling-surface being placed so as to meet the inflowing fluid. The diminished part S of the circumferential portion 0 of the casing provides aclear passageway for the expended fluid to pass into the exhaust-port T. The enlargement of. this passageway also be accomplished by othermeans, such as by the removal of a portion of the casing or by providing a set-off inthe casting. The inner facing-strips U, formed on the side plates F, (m'de Figs. 3 and 4,) are recessed to receive the flexible directingplates V, which are secured: in position and. provided with set-screws means for adjusting them against the-sides of the disk. A similar plate X is also placed in a recess formed in the circumferential part 0, and is similarly adjusted, so as to slightly bear upon the rations R. The object of these flexibleplates is to confine the pressure fluid sufficiently to prolong its operating influence and to prevent its dispersion or vitiation at too early a stage of the operation. The fluid-pressure chamber Y is situated in the circumferential, part 0 of the outer casing and may be either fixed or removable, essary, and if removable may be made reversible to operate the motor in either direction. The said chamber is in direct communication with the supply-pipe Z, from. whence the fluid used enters the chamber and passes out of the slot a, which ismade the desired width and length, the latter not necessarily being the same width as the disk-serrationsior pressure-chamber. (Vz'de Fig. 7). i

To provide for an absolutely-free egress of the pressure fluid and in order to create a reaction-chamber b, the obstructive outer portion of the metal surrounding the slot is removed both from the bottom portion 0 and the front part d, so that only the slot remains, and the surfaces which have thus been created form, together with the impelling and. following portions of the disk-serrations, a: peculiarly-constructed chamber, in whichthe operating fluid performs the workofv rotating usted expeditiously K, with their set-screws, are provided, so thatvent of wear taking ates may beindependent of that W or other, suitable points ofthe disk-seras may be considered necprojecting lip the disk most Getawa below the slot a,

The action of this rotary. o is lows: the operating fluidhavringfgn'te chamber Y and passed outflthrkrhghjthe j into the reaction-chamberb is] by the p construction of that chamber caused t into the serrations, actingupon theimpel gi surfaces confined between the. saidtoharn r b and the directing-plates V and. and p ofducing a rotary movement" of high velocit resulting in the developmentofigreatii'orcm A feature of this invention isthatilthe ex ipended fluid when.dischargfed fromthe out- ,let-port would in the case of steam have ex- Jpended its energy to such an extent as to appear. in the form of vapor wholly expanded.

The form and locationof the exhaust. may be varied to suit the changing conditions of manufacture, which would vary according to the purpose to which the motor would beaplied. p To regulate the ingress of the pressure fluid, governors of any suitable type may be used, the pulley h being provided for that purpose.

Where double serrations are provided upon one disk, as in Figs. 8, 9, and 10, the associated pressure-chambers and director-plates, together with the outlet passages and ports, are suitably placed to obtain the desiredreverse motions; but where casings are provided with separate rotary disks to operate in reverse directions the inoperative disk for the time being serves as a fly-wheel. In either casethe pressure-chambers and the directorplates and other necessary. associated parts occupy the relative positions essential to ob taining motion in the desired direction. This form of. rotary motor in either of the forms describediis serviceable for many purposes to which engines are adapted.

Having now described my invention, I do sire tostate thatI am aware thata revolving disk and an outer casing are not in themselves novel, but when. associated with. the peculiar features embraced by. this invention.

they are capable of producing results not heretofore obtained. Therefore,

What I claim as new, and desire to secure by Letters Patent, is

1. In rotary motors of the class set forth, the combination, With a fluid-pressure chamber, of, an adjustable plate for regulating the dimensions of the outlet-slot of the said chamber and a projecting lip extending from the rear wall of the said chamber under the Whole of the said chamber and beyond the opposite or forward wall thereof, as described and shown, and for the purposes set forth.

2. In rotary motors of the class set forth, an upper adjustable plate and adjustable side plates, placed within the casing in close proximity to the fluid-pressure chamber, and a projecting lip extending from the rear wall of the said chamber under the whole of the said chamber and beyond the opposite or forward wall thereof, as described and shown, and for the purposes set forth.

3. In rotary motors of the class set forth, a projecting lip, a passage in close proximity thereto, an upper and two side directingplates, and, serrations constructed upon a rotary disk, all forming a reaction-chamber in communication with an outlet-slot of a fluid-= pressure chamber, as herein described and shown, and for the purposes set forth.

4. In rotary motors of the class set forth, the combination, with a casing having upper and side adjustable director-plates, of, adjustable stuffing-boxes and foot-plates provided with means for adjusting the position of said casing relatively to an inclosed rotary disk whose serrations are in contact with a projecting lip of a fluid-pressure chamber, as described and shown and for the purposes set forth.

5. In rotary motors of the class set forth, an outer casing having upper and side director plates and provided with inner side facing strips, the lower part of such casing being of a diminished thickness so as to form an out let-passage for the expended fluid, and communicatin g with an eXhaust-port,as described and shown.

In witness whereof I have hereunto set my hand in presence of two witnesses.
